How to build software on Solaris 11/SPARC
Today we'll figure out the default build flags used by the Solaris Userland Consolidation.
We already used them while building nginx, see nginx on Solaris 11.3 SRU 19 with ECC crypto and HTTP/2 support.
We need a compiler before we can build anything. My preferred choice is the Solaris Developer Studio compiler. You can download a tarball at Developer Studio or request a solarisstudio
repository certificate at Oracle Repositories.
Either way, you should have a decent compiler now.
$ /opt/developerstudio12.5/bin/cc -V cc: Studio 12.5 Sun C 5.14 SunOS_sparc 2016/05/31
Good. Let get the default 64bit *FLAGS used to build software from shared-macros.mk.
# Enables large file support for components that have no other means of doing # so. Use CPP_LARGEFILES and not the .32/.64 variety directly CPP_LARGEFILES.64 := $(shell getconf LFS64_CFLAGS) CPP_LARGEFILES = $(CPP_LARGEFILES.$(BITS)) # XPG6 mode. This option enables XPG6 conformance, plus extensions. # Amongst other things, this option will cause system calls like # popen (3C) and system (3C) to invoke the standards-conforming # shell, /usr/xpg4/bin/sh, instead of /usr/bin/sh. Add studio_XPG6MODE to # CFLAGS instead of using this directly CPP_XPG6MODE= -D_XOPEN_SOURCE=600 -D__EXTENSIONS__=1 -D_XPG6
This should equal the following CPPFLAGS:
CPPFLAGS="$(getconf LFS64_CFLAGS) -D_XOPEN_SOURCE=600 -D__EXTENSIONS__=1 -D_XPG6"
Let's do the same for CFLAGS.
BITS ?= 64 MACH := $(shell uname -p) MACH64_1 = $(MACH:sparc=sparcv9) CC_BITS = -m$(BITS) studio_XBITS.sparc.64 += -xarch=sparcvis -xchip=ultra2 studio_XBITS = $(studio_XBITS.$(MACH).$(BITS)) # Turn on recognition of supported C99 language features and enable the 1999 C # standard library semantics of routines that appear in both the 1990 and # 1999 C standard. To use set studio_C99MODE=$(studio_C99_ENABLE) in your # component Makefile. studio_C99_ENABLE = -xc99=all # Allow zero-sized struct/union declarations and void functions with return # statements. studio_FEATURES_EXTENSIONS = -features=extensions studio_OPT.sparc.64 ?= -xO4 studio_OPT ?= $(studio_OPT.$(MACH).$(BITS)) # Studio PIC code generation. Use CC_PIC instead to select PIC code generation. studio_PIC = -KPIC -DPIC # The Sun Studio 11 compiler has changed the behaviour of integer # wrap arounds and so a flag is needed to use the legacy behaviour # (without this flag panics/hangs could be exposed within the source). # This is used through studio_IROPTS, not the 'sparc' variety. studio_IROPTS.sparc = -W2,-xwrap_int studio_IROPTS = $(studio_IROPTS.$(MACH)) # Control register usage for generated code. SPARC ABI requires system # libraries not to use application registers. x86 requires 'no%frameptr' at # x04 or higher. # We should just use -xregs but we need to workaround 7030022. Note # that we can't use the (documented) -Wc,-xregs workaround because # libtool really hates -Wc and thinks it should be -Wl. Instead # we use an (undocumented) option which actually happens to be what # CC would use. studio_XREGS.sparc = -Qoption cg -xregs=no%appl studio_XREGS = $(studio_XREGS.$(MACH)) # Set data alignment on sparc to reasonable values, 8 byte alignment for 32 bit # objects and 16 byte alignment for 64 bit objects. This is added to CFLAGS by # default. studio_ALIGN.sparc.64 = -xmemalign=16s studio_ALIGN = $(studio_ALIGN.$(MACH).$(BITS)) # Studio shorthand for building multi-threaded code, enables -D_REENTRANT and # linking with threadin support. This is added to CFLAGS by default, override # studio_MT to turn this off. studio_MT = -mt CFLAGS.studio += $(studio_OPT) $(studio_XBITS) $(studio_XREGS) \ $(studio_IROPTS) $(studio_C99MODE) $(studio_ALIGN) \ $(studio_MT)
This should equal the following CFLAGS:
CFLAGS="-m64 -xO4 -xarch=sparcvis -xchip=ultra2 \ -Qoption cg -xregs=no%appl -W2,-xwrap_int -xc99=all -xmemalign=16s \ -mt -KPIC -DPIC"
And last but not least, for LDFLAGS.
# set the bittedness that we want to link LD_BITS = -$(BITS) # eliminate unreferenced dynamic dependencies LD_Z_IGNORE = -zignore # eliminate comments LD_Z_STRIP_CLASS = -zstrip-class=comment # use direct binding LD_B_DIRECT = -Bdirect # build a PIE binary # to enable creating a PIE binary, add LD_Z_PIE_MODE = $(LD_Z_PIE_ENABLE) # to the component makefile, and ensure that it's built PIC (CC_PIC_ENABLE). LD_Z_PIE_ENABLE = -ztype=pie # by default, turn on Address Space Layout Randomization, non-executable # stack and non-executable heap for ELF executables; ASLR_ENABLE = -zaslr=enable NXSTACK_ENABLE = -znxstack=enable NXHEAP_ENABLE = -znxheap=enable # Create a non-executable bss segment when linking. LD_MAP_NOEXBSS.sparc = -M /usr/lib/ld/map.noexbss # Create a non-executable data segment when linking. Due to PLT needs, the # data segment must be executable on sparc, but the bss does not. # see mapfile comments for more information LD_MAP_NOEXDATA.sparc = $(LD_MAP_NOEXBSS.$(MACH)) # Page alignment LD_MAP_PAGEALIGN = -M /usr/lib/ld/map.pagealign # Default linker options that everyone should get. Do not add additional # libraries to this macro, as it will apply to everything linked during the # component build. LD_OPTIONS += $(LD_MAP_NOEXDATA.$(MACH)) \ $(LD_MAP_PAGEALIGN) $(LD_B_DIRECT) $(LD_Z_IGNORE) \ $(LD_Z_STRIP_CLASS)
This should equal the following LDFLAGS:
LDFLAGS="-m64 -M /usr/lib/ld/map.noexbss \ -M /usr/lib/ld/map.pagealign -Bdirect -zignore \ -zstrip-class=comment -ztype=pie \ -zaslr=enable -znxstack=enable -znxheap=enable"
Some software also doesn't like the Solaris nm, so we'll use GNU nm instead. See configure.mk.
# temporarily work around some issues CONFIGURE_ENV += "ac_cv_func_realloc_0_nonnull=yes" CONFIGURE_ENV += "NM=/usr/gnu/bin/nm"
Putting everything together, here is an example of how I usually invoke configure when building FOSS:
$ getconf PATH
/usr/xpg6/bin:/usr/xpg4/bin:/usr/ccs/bin:/usr/bin:/opt/developerstudio12.5/bin:...
$ PATH=$(getconf PATH) ./configure PKG_CONFIG_PATH=/usr/lib/64/pkgconfig NM=/usr/gnu/bin/nm SHELL=bash MAKE=gmake \
CPPFLAGS="$(getconf LFS64_CFLAGS) -D_XOPEN_SOURCE=600 -D__EXTENSIONS__=1 -D_XPG6" \
CC=cc CFLAGS='-m64 -xO4 -xarch=sparcvis2 -Qoption cg -xregs=no%appl -W2,-xwrap_int \
-xc99=all -xmemalign=16s -mt -KPIC -DPIC' \
LDFLAGS='-m64 -M /usr/lib/ld/map.noexbss -M /usr/lib/ld/map.pagealign \
-zaslr=enable -znxstack=enable -znxheap=enable \
-Bdirect -zignore -zstrip-class=comment -ztype=pie' \
--prefix=/opt/local ...
$ PATH=$(getconf PATH) gmake
...
